I recently updated because of a missing wifi driver (Qualcomm Atheros Device [168c:003e] - ath10k_pci) to 4.2.0-18-generic/firmware_1.149.2.

The Wifi is still not working (even with the driver).

lspci -knn | grep -i Net -A2

rfkill list

sudo lshw -C Network

dmesg

edit:

The firmware-5.bin for QCA6174 was not found in the lib/firmware/ath10k/QCA6174/hw3.0. Therefore I copied it from the hw2.1 folder. The other thing was that the ath10k.conf was missing.

sudo nano /etc/modprobe.d/ath10k.conf

"options ath10k_core skip_otp=y"

but after reboot there is still no wifi.

There seems to be an answer now / or a least a work around - worked for me.

Thank you to Dennis.

Be careful that the files are named properly, when copying it to /lib/firmware/ath10k/QCA6174/hw3.0/
